Floating calipers are a type of brake caliper used in disc brake systems. They consist of a single piston that pushes against the brake pad on one side of the disc, while the caliper itself can slide slightly on its mounting bracket. This design allows the caliper to adjust to the wear of the brake pads, ensuring even pressure is applied to the disc. The main advantage of floating calipers is their simplicity and cost-effectiveness. They are commonly found in many vehicles, including passenger cars and light trucks. Their design helps improve braking performance while reducing the overall weight of the braking system.
